Debugging Prefect code on your local machine isn't much different from debugging any other Python code. Here are some general steps you might take to debug Prefect code: 1. Use Print Statements: You can insert print statements in your task functions to see what values are being passed and returned. 2. Python Debugger: Use Python's built-in debugger,
pdb
, by adding
import pdb; pdb.set_trace()
to set a breakpoint in your code. When execution reaches this point, you'll enter an interactive debugging environment. 3. Logging: Prefect has a built-in logging system that you can use to log messages at various severity levels. You can configure the logging level to get more detailed information about what's happening in your flows and tasks. 4. Unit Tests: Write unit tests for your tasks to ensure they behave as expected in isolation. 5. Execute Flow Locally: Run your flow locally using
flow.run()
to see how it behaves without the orchestration backend, and check if there are any immediate issues. 6. Visual Debugging: Use a visual Python debugger that integrates with your code editor or IDE. 7. Inspecting State: Inspect the state of tasks after a run to see where they may have failed or encountered issues. If you need to look up more detailed information on debugging strategies or how to use logging and inspecting states within Prefect, would you like me to find specific documentation or resources for you?
